MACHINYE7FOR CUTTI'NG'MANTLES FOR INCANDESCENT'LIGHTSOROTHER MATERIAL.

srEcIFIcATIoN forming part of Letters Patent No. 760,760, dated May 24,1904.

Be it known thatl, JOHNAERIISSELL, a citizen of the United States, residing at Chicago,

in the county of Cook and State of ,Illinois,

- ments in Machines for Cutting Mantles for .tles are producedea have invented certain new-fand useful Improve Incandescent .Lightsor other Material, of which the following isa full, clear, and: exact specification.

, 'My invention; .relatesItof machin'es for cutting strips of material Into sections of uniform length, and more particulafly to machines for cutting flexible strips ofjfabric, such as the knitted, tubes from which incandescent man- Thein vention has, for its object to provide improved;-. means. for automatically point of engagement with the goods will not vary, and hence the feed may he made to engage the. goods at:.a point contiguous tothe advance end regardlessof the length of the stroke. I Y

Another'object oftheinvention is to sever the goods by shearing-blades intersecting the .support on which the goods ,rest and across "said support at a point intermediate the extremities of the stroke of the feed.

Withthese endsinview my invention consists in certain features of novelty in the constru ction, combination; and-arrangement of parts by whichthe said objects and certain other objects, hereinafter appearing are atta'inj ed', all as fully described with reference to ticularly pointed out in the claims.- In the saiddrawings, Figure 11s a side'eleva- 0 line 4 4, Fig. 5.

, .tion of my improved-machine. Fig. 2 is a plan View thereof. Fig. 3 is a verticallongitudinal. section on the line 3 3, Fig. 2. Fig. 4 is a, detail vertical sectional view, of the pressers, showing the relation of the same to one of the shearing or cutter blades", taken on the Fig. 5' is a plan view thereof.

" Application filed February 11,1903. SerialNo. 14Z,939. momma;

Fig. 6 is a vertical cross-section of the machine on the line 6 6, Figs. 1 and 3. .Fig. 7 is a detail perspective view of the feeder hereinafter described.v Fig. 8 is adetail side ele- Nation of the feederactuatingT-.arm or lever, showing its relation to the feeder and adjusted to produce the maximum length of stroke.

Fig.9 is a similar view showing the device adjusted for producing the minimum length of stroke. Fig. 10 isalongitudinal sectional View taken "on the line 10 10,..Fig. 9. r

As iswell understood by those. skilled in the art, mantles or incandescent. lamps are produced by first weaving a'tubezof-iany suit 7 able thread and then cuttingthe tube into sections of proper length and -subsequently' treating them by the various processes ,for V producing the non-combustible ash.

- {My invention asishown inthe drawingsis especially, adapted for-rapidly and accurately ,feeding'this tube automaticallypast a suitable cutter; but it will nevertheless be understoodthat the invention is also applicable for cutting other material into sections-of a given length. vWhen employed for cutting incan descent mantles, the machine is provided with asuitable race or support forthe goods or tubular strip, which isshown as comprising a bottom 1 and .side-wallsQ, arrangedat the proper distance apart for receiving and guiding the tube whenflattened out. The bottom of the race is provided with a' number of-longitudinal slots 3, and projecting upwardly through these slots are a 'number of'hooks or curved needles 1, which constitute parts of a feeder which is shown in Fi 7 as com risa a P inga bar 5, in which the needles4 are secured, and a sliding crossrhead 6,-which.car-

ries the bar 5 andis mounted-on a longitudi-.-.

nal'guide-rod 7, arranged, lengthwise of the race and preferably below the 'bottomthereof. The'bar or rod 7, is mounted at its ends intwo rocker-arms 8 9, which. are rigidly secured to arocker-shaft 10,.J 0urnaled in any suitable supports, such as standards 21 24: of the main frame, and the shaft -10 is provided with a crank-arm 12, pivotally secured to the upper end of an adjusting and supporting rod 13, whose lower end is supported 'upon a lever 14, having an antifriction-roller l5 resting upon a cam '16 on main shaft 17, and the cam 16 is formed with two concentric peripheries 16*16", one of smaller diameter than the other, connected together by two straight portions 16 16 and which are so proportioned and relatively arranged as to hold the needles 4 of the feeder. in their elevated position projecting through the slots in the bottom of the race and in engagement with the goods throughout the length of their feeding stroke, the roller during this time being supported by the larger concentric periphery 16, and thereby holding the rod 7 at the limit of its upward movement; but when the feeder reaches the limit of its stroke on said rod 7 the roller 15 rides downwardly on one of the inclined or straight portions 16 16 and thence rests on the smaller concentric periphery 16 while the feeder is making its return stroke with the'needles 4 out of engagement with the goods. In order, however, that the extent to which the needles penetrate the goods may be varied to suit the requirements, the rod 13 is made adjustable on the lever 14 by providing the rod with a set-screw 18, threaded thereon and passing through and resting upon a boss 19 on lever 14. Lever 14 maybe supported and held in place in any suitableway. One end is shown as pivoted at 20 to standard 21, while the other end is slotted at 22 and fits under a headed guide-screw 23 on standard 24.

The cutter for severing the goods preferably consists of two shearing-blades, one of whichis preferably fixed above the race, while the other moves upwardly into engagement therewith from below. The fixed blade is shown at 25 and is secured by screws 26 or other suitable devices to any suitable supports 27, mounted on table 1", part of which constitutes the bottom of the race. The movable knife or'blade is shown at 28 and preferably has a shearing or oblique edge, while the edge of blade 25 may be horizontal or parallel with the face of the race. The blade 28 is secured to a pivoted arm 29, rigidly mounted on a rocker-shaft 30, journaled under the table 1. The outer end of shaft 3.0 is provided with a rocker-arm 31, as better shown in Fig. 1, which is operatively attached by connecting-rod 32 to a wrist-pin or other suitable crank 33 on disk 34, secured to shaft 17, so that at each rotation'of the shaft the blade 28 will make its upward stroke to cooperate with blade 25 in severing the goods. The cutting edge of blade 25 is located a slight distance above the face of the race, and the blade 28 intersects therace, passing upwardlyin so doing through a transverse slot 35, severing the bars or portions of the race between the longitudinal slots 3 in the bottom of the race at a point just back of the blade 25. The goods to be cut into sections are fed along the race from the right-hand end, as shown in Fig. 3, and the knife severs the sameat a time when the needles of the feeder are at the left-hand end of their stroke, thus leaving the forward end of the main portion of the goods behind the blade 25, to which point the needles of the feeder must return and rise upwardly through the race in order to again engage the goods for pulling the same forward the proper distance before the movable blade of the cutter again comes into operation. Consequently the edge of the blade 25 is located sufiiciently high above the race to avoid being engaged by the needles, and in order that the goods may be held down against the race while the needles are rising into engagement therewith, so as to insure the penetration of the goods by the needles, I provide a presser, preferably consisting of a shoe 36, extending across the race and secured to a pivoted rocker-shaft 37 journaled in the side walls of the race and having a weighted handle 38, which tends to hold the shoe 36 yieldingly against the goods, the shoe being provided with slots 37 for the passage of the needles 4.

' In order that the goods may not undergo a retrograde or backward movement when the mantle is severed from the end thereof and before the needles again engage the same, the presser 36 is provided at its forward edge with a number of teeth 39, which project downwardly therefrom a sufficient distance into the goods to hold the same from slipping backwardly until the needles rise. These teeth 39 are shown as formed on a plate 40, which is separate from the plate or presser 36 and is also secured to the shaft 37 and movable in unison with the presser 36 and virtually a part thereof. The plate 40 is also slotted, as shown at 41, for the passage of the needles 4. When the movable blade 28 rises and severs the fabric, it pushes the end thereof upwardly considerably above the lower edge of blade 25, and in orderto insure against such end curling up in front of teeth 39 and engaging the side of blade 25 without passing freely thereunder a second presser 42 is employed and arranged, preferably, directly above the first-deseribed presser as close to the blade 25 as possible without combining thereagainst, while being at the same time pivoted to swing on an are. This presser 42 is preferably pivotally mounted upon the shaft 37 by means of arms 43, but is independent of said shaft and of the presser 36,

so that it may move upwardly with the blade 28 Without interfering with the position of presser 36. The presser 36 is held down by gravity, as before described; but the presser 42 is preferably pressed downwardly by means of spring 44. In order that the presser 42 may rise out of the way of the blade 28 when the latter ascends, the arm 29, which carries said blade, is provided with an adjustable rod 45, secured in the arm in any suitable way, as by means of set-screw 46, and adapted to strike a lug 47 on the side of presser 42 as soon as the upper corner of blade 28 reaches the blade 25, the time at which the presser 42 begins to mal position and. prevented from descending. too far by any suitable stop '48, projecting from one of the side walls 2v of the race, the plate 40 and shoe or presser 36 being-notched at 49, so as to pass stop 48, should -..it' be desired to elevate them in inserting the-end'ofthe goods to a position Where the same may be engaged by the feeder, it being understood that both pressers may be'thus elevated simultaneously-by the handle or lever 38.; The presser 42 may also, if desired, be'providedwith slots 50, registering with the slots in the,

presser 36- and plate 40, for the'passageofgthe needles 4. s 1 I r 1 a In order to insure against the possibilityof the needles 4 getting out of line with the slots. 3 in the bottom of the race where-fthe .race is intersected by the cutter, the cross-headfl6 or some other suitable part of the feeder isprovided. with a number of guide-plates-51, lo.- cated-in line with and in advance of-the needles-4 and whichaare-so positioned that they do not entirely cross the, slot 35,. but remain between the" longer ends of the-bars of-the slotted ra'ce. a

The feeder is reciprocated on its guide rod r or bar 7 by means ,ofia pivoted-arm or. =.-l'ever, preferably consisting of two jointed members 52 53-, the upper oneiof which is connected by a link 54 to the side of the sliding dross-head 6, While the lower member -53.is pivoted atz55 in a suitable support 5.6, mounted on a base 57 upon which the balance of the mechanism is also supported. This jointed armor-lever is oscillated by an eccentric 58 or any-other'suit-. able connection with driving-shaft17, whose strap is connected by rod 59 to'a stud 60, fit.- ting in a slot 61 in: member-53, so that by changing the positionofithe stud. -with ref.

erence to the length of member 53 the. length of the stroke of thefeeder may beaccordingly varied, thereby providing means-for cutting off sections-for i nantles of various lengths; Inasmuch, however, as the feeder must always startfrom the same point withgreference tothe length of the-race, I provide means-where-r by the variation in the length of the feeding stroke does not-vary the initial position of the.

feeder,:or, in other words, the movement of the stud'60 in the sl0t'61 does not alter the position of the upper end of thejointed arm where i it is connected to the feeder. An efficient and simple :means for accomplishing this will now be described. As shown in Figs. 8 to 10;-the arm or lever member 53 is .provided onvone side with a slide 62, whose upper end is provided with an. oblique slot 63, engaging over a stud or-pin 64 on the arm member 52. This ing a longitudinal slot, a feeder traversing slot 63 is arranged approximately at an angle of forty-five degrees to the longitudinal ax'is' of slide 62,-and the slide is preferably connected with the stud 60 by any suitable means, such as set-screw 65, which also serves as a pivot for-rod 59, so-fthat when the slide is moved in one direction for altering the position of Stud 60 in slot 61 the two members 52 53- of the arm or lever will .be simultaneously turned at an angle to each other a degree proportionate. to the dis: tance which the stud 60' is moved along slot 61, the slot.63 serving more as ameans of. peri mitting-the. arm member 53 to move at its upper end' to accommodate stud 60 without mov:

ing the upper end of arm member 52 than as a means of contributing to this movement;

:to allow. the armmembers to move relatively without pulling the upper member downwardly. =Hence the-lower end of arm member 52 is slotted at 68, and passingthrough this slot and also through member 53-and a longitud'inal slot 69-in-slide 62 isa pivoted bolt'70,

whosehead 71 serves to hold slide 62 in place.

[hedriving-shaft 17 may be driven .in any suitable way. I have'shown it provided with a hand-Wheel 72 and a belt wheel or pulley 73, both. detachably secured by screws 7 4' to the shaft, so that either may beused. 2

1 Thesections-of the-fabric severed from the main piece fall from-the end of the race down asu'itable chute 7 5, and, if desired, the opposite end of the base 57 may be provided with a folding extension -76,-upon which lies the main piece of the fabric being cut.
